after spending 7/9 of a three hours examination, a student left the exams hall. How many minutes has he to complete the duration of the examination.​

Answer:

y = -4

Step-by-step explanation:

since f(y) = 9, you know the equation is equal to 9

9 = [tex]\sqrt{y+29}[/tex] - y

81 + 18y + y^2 = y + 29

y = -4

the awnser is graph A.

you find the two point that the line is going through and count the squares going up (rise) and count the squares going a cross (run). and that is the slope and the -3 is where the point is on the y intercept

Answer:

the diameter is 24 so the ray is 12

circonference = 2*pi*R = 2*3.14*12= 75.36

Answer:

Step-by-step explanation:

There are a lot of conversion factors involved in this question.

First of all the radius of Mercury's orbit is 0.4 times that of the earth. The earth's distance from the sun is about 93 million miles. So Mercury's distance or radius is 93 * 0.4 = 37.2 million miles.

The circumference = 2 * pi * r

The circumference = 6.28 * 37200000 = 233616000  miles

This is accomplished in 88 days.

88 days [24 hours/day] * [3600 sec / hour] = 7603200 seconds

88 days = 7603200 second

Rate of travel = miles / second

Rate of travel = 233616000 / 7603200

Rate of travel = 30.726 miles / second

This number was not given so I had to derive it. The official number does not disagree a great deal from this number. It just depends on what constants you use.

1 mile = 1.6 km

30.725 miles = x           Cross multiply

x = 1.6 * 30.725

x = 49.16 km/ second

I cannot go any further because you have not provided any givens. The answers do vary quite a bit because I have assumed that Mercury's orbit is a circle. It really is not. It is more like an ellipse.  

The official speed in km/sec = 47 which means the answer I have given is very close. A more accurate answer would require that you put the numbers in the blanks that you were given.

Answer:

A) 0.01

B) 0.07

Step-by-step explanation:

We are given;

P(accidents last year) = 0% = 0

P(accidents this year) = 6% = 0.06

P(accidents last year | accidents this year) = 10% = 0.1

A) We want to find the percentage of the employees will experience lost-time accidents in both years.

From multiplication rule in probability, we know that;

P(A & B) = P(A) × P(B|A) = P(B) × P(A|B)

Thus;

P(accident in both years) = P(accidents this year) × P(accidents last year | accidents this year)

P(accident in both years) = 0.06 × 0.1

P(accident in both years) = 0.006

To 2 decimal places gives; 0.01

B) from the addition rule, we know that;

P(A or B) = P(A) + P(B) - P(A & B)

Thus;

P(accident last year or this year) = P(accidents last year) + P(accidents this year) - P(accident in both years)

P(accident last year or this year) = 0 + 0.06 + 0.006 = 0.066

To 2 decimal places = 0.07

A function is even if f(x)=f(-x), and odd if f(x)=-f(-x). If a function satisfies neither of these, it is neither even nor odd.

[tex]f(x)=-3x+1\\f(-x)=-3(-x)+1=3x+1[/tex]

Since f(x) is equal to neither f(-x) nor f(-x), the function is neither even nor odd.

Answer:

A

Step-by-step explanation:

Just took the test

The statement that asserts a true claim would be:

A). The height is approximately r units and the base length is approximately πr units.

The sector is described as an element of the circle or a part that extends to the center.

In the given figure, the height of the congruent sectors would be equivalent to r units as the radius is r units.

While the length of its base would be equivalent to πr units to denote the base length.

Thus, option A is the correct answer.

Answer:

3/25

Step-by-step explanation:

There are 10 total marbles

P(yellow) = yellow/total = 4/10 = 2/5

We replace it so there are 10 marbles

P(2nd marble blue) = blue /total = 3/10

Multiply the two probabilities together

P(yellow, replace, blue) =2/5*3/10 = 3/25

Answer:

[tex](x - 2)^2 + (y +4)^2 = 25[/tex]

Step-by-step explanation:

Given

[tex](h,k) = (2,-4)[/tex] --- center

[tex]r = 5[/tex] --- radius

Required

Determine the equation

The equation of the circle is:

[tex](x -h)^2 + (y - k)^2 = r^2[/tex]

From the given parameters, we have:

[tex]h = 2[/tex]

[tex]k = -4[/tex]

[tex]r = 5[/tex]

So:

[tex](x -h)^2 + (y - k)^2 = r^2[/tex]

[tex](x - 2)^2 + (y --4)^2 = 5^2[/tex]

Express -- as +

[tex](x - 2)^2 + (y +4)^2 = 5^2[/tex]

Evaluate the squares

[tex](x - 2)^2 + (y +4)^2 = 25[/tex]

• Equal sides of an isosceles triangle = 2cm shorter than the length of the third side.

• Length of the third side.

Let the third side be c.

Also, two equal sides be a and b.

According to the question,

[tex] \longmapsto [/tex] a = ( Third side - 2 ) cm

[tex] \longmapsto [/tex] a = ( c - 2 ) cm

Similarly, length of b(second side) will also be same as a and b are two equal sides of an isosceles triangle.

[tex] \longmapsto [/tex] b = ( c - 2 ) cm

Now, we know that :

★ Perimeter of ∆ = Sum of all sides

[tex] \longmapsto [/tex] 35 = a + b + c

[tex] \longmapsto [/tex] 35 = (c - 2) + (c - 2) + c

[tex] \longmapsto [/tex] 35 = c - 2 + c - 2 + c

[tex] \longmapsto [/tex] 35 = c + c + c - 2 - 2

[tex] \longmapsto [/tex] 35 = 3c - 4

[tex] \longmapsto [/tex] 35 + 4 = 3c

[tex] \longmapsto [/tex] 39 = 3c

[tex] \longmapsto [/tex] [tex] \sf \dfrac{39}{3} [/tex] = c

[tex] \longmapsto [/tex] 13 = c

So, third side of the triangle is 13 cm.

It's totally correct with no doubt

Answer:

[tex]y=9x-13[/tex]

Step-by-step explanation:

Slope-intercept form is [tex]y=mx+b[/tex], where m is the slope, and b is the y-intercept. They tell us the slope is 9, so [tex]m=9[/tex]. They also tell us that the y-intercept is (0,-13), which means that [tex]b=-13[/tex]. Plugging both of those values in gives us the equation:

[tex]y=9x-13[/tex]

The median is going to be 23.
